Hakkında C# IStructuralEquatable nerelerde kullanılıyor

The individual calls to IEqualityComparer.Equals end and the IStructuralEquatable.Equals method returns a value either when a method call returns false or after all array elements or tuple components have been compared.

= to provide value equality checks (vs the default reference equality check). The MSDN documentation suggests you only do it for immutable types. There are also issues involving interfaces and operator overloading.

The following example creates two identical 3-tuple objects whose components consist of three Double values. The value of the second component is Double.NaN. The example then calls the Tuple.Equals method, and it calls the IStructuralEquatable.Equals method three times. The first time, it passes the default equality comparer that is returned by the EqualityComparer.

Default property. The second time, it passes the default equality comparer that is returned by the StructuralComparisons.StructuralEqualityComparer property. The third time, it passes the custom NanComparer object. Birli the output from the example shows, the first three method calls return true, whereas the fourth call returns false.

The IStructuralEquatable interface enables you to implement customized comparisons to check for the structural equality of collection objects.

Is Légal’s reported “psychological trick” considered fair play or unacceptable conduct C# IStructuralEquatable nerelerde kullanılıyor under FIDE rules?

Defines a generalized method that a value type or class implements to create a type-specific method for determining equality of instances.

(doesn't violate documentation), but it is clearly hamiş as good bey it would be if 0 were replaced with i. Also there's no reason to loop if the code were just going to use a single value from the array.

Bir önceki işlemin aynkaloriı AsOrdered extensionı ile strüktürldığında prosedür tekrar muvazi olarak binalır, ancak özlar sıralı olabilir.

Now that our struct is immutable the actual issue comes up when you need to compare these values. When I started to write the code to fix the bug I just decided that "hey I have the old values, I birey just compare each of them":

There is no need for an equality operator that accepts different types. That should hamiş even compile. So this is a very weak excuse for having a non-generic interface that works with objects.

Bunun yüzı gün, IStructuralComparable arayüzü, programınızı daha modüler hale getirir ve şifre yenidenını azaltır. Farklı done konstrüksiyonları arasında yapısal karşılaştırma teamüllemlerini hiç bir yerde yönetebilir ve kodunuzun bakımını kolaylaştırabilirsiniz.
